Improvement in peg-wood



UNITED STATES PATENT FFIGE.

WILLIAM N. LINNELL, OF CAMBRIDGE, ASSIGNOR TO ARZA B. KEITH, OF

BRAINTBEE, MASSACHUSETTS.

IMPROVNIENT IN PEG-WOOD.

Specification forming part of Letters Patent No. 117,436, dated July 25, 1871.

To all whom it may concern:

Be it known that I,W1LL1AM N. LINNELL, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Peg-Vood; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of .this specification, is adescription of my invention, suf- Yflcient to enable those skilled in the art to practice it.

In machine-pegging boots and shoes it is customary to use ribbons or strips of peg-wood of a form, in section, corresponding to the forni of a common wood peg, from the end of which strip each peg is cut or split. .y These pegs so cut have always been of the common form, or straightsided pointed pegs, a section of the peg-wood being a rectangle except .as to a tapering or wedge-shape at one edge.

AIt is well known thatu when a boot or shoe-sole becomes dry and hard and the pegs shrink they draw out from the sole` or from the upper, and to the ruin or injury oftheboot or shoe. To remedy this I form the peg-wood so that pegs cut from it have projections or recesses upon two opposite sides, between which projections or into whichl recesses the leather fays when the peg is driven,

so that the projections form obstructions that resist withdrawal of the peg from the leather. It is in peg-Wood strips or ribbons having corrugated or denticulated surfaces that my invention consists.

The drawing represents a peg-wood coil or ribbon embodying my invention.

, TBCGSSCS 0.

On each side of the strip I form recesses (o parallel with the opposite edges of the strip, and when a peg is cut off" it has the form shown at B, the .two opposite split surfaces being parallel, as in ordinary pegs, and the other two opposite surfaces having the teeth or projections b and The parallel ribs or recesses may be formed in or 0n the surfaces of the strip b i any suitable means, and they may be made either upon one surface only or upon both. surfaces; and there may be on each or either surface a number of recesses or but one. For the best results, however, I prefer a formation substantially like that shown in the drawing. The projections upon the sides of the pegs act as obstacles to prevent separation of the leather and the pegs, and insure a permanent union of the parts connected by the pegs. The recesses may be made by suitable saws or other tools attached to the machine that cuts the pegwood coil, or they may be made by independent tools or saws. In either case they are very easily formed, and do not add materially to the cost of the peg-wood.

I claim- As a new article of manufacture, a peg-wood ribbon or band, formed with one or both sidesV serrated7 denticulated, or corrugated, substantially as described.

Executed this 3d day of June, A. D. 1871.
